Which statement best contrasts innate behavior with ontogenetic behavior?

• A. Innate behavior is automatic and does not require learning; Ontogenetic develops over the lifetime
• B. Innate behavior develops over lifetime; Ontogenetic is automatic
• C. Innate requires reinforcement; Ontogenetic does not
• D. Innate is influenced by environment only; Ontogenetic is strictly genetic

Answer: (A)

Innate behaviors are inborn and automatic, not requiring learning to occur. They’re triggered by specific cues and tend to be consistent across individuals. Ontogenetic behaviors, by contrast, develop as the animal grows and gains experience—these are learned or shaped through training, practice, and environmental interactions over a lifetime. So the statement is correct because it cleanly contrasts automatic, unlearned action with behaviors that are acquired or modified through experience. The other options mix up the roles of learning, reinforcement, environment, and genetics in ways that don’t fit how innate and ontogenetic behaviors typically operate.
